I have shot Noslers since, well just say it was a long time ago. There is no turning back for me - other than they are to dang expensive now. I bought a ton of them years ago and still have enough left to last me - I am old.
I shoot two of them.... I shoot .451/260's for deer and .458/300 for elk. I use MMP sabots for both. I use a HPH-24 black sabot in all of the rifles I have except the White and that one takes a HPH-12. And for the .458's I use a MMP .458/50 cal Orange sabot.
A point of information the .458's are a rifle bullet and built with a slightly thicker copper jacket, the .451/300 grain HG's (hand gun) bullets are also great bullets and if you a shooting deer @ the closer ranges might perform a bit better for you than the .458's - on a thin skinned whitetail they can get in and out on a big hurry - that is why I use the 260 on deer - it is really a deadly bullet... but if you are are hunting both on the same hunt go 300.
I am a T7 user have not made the switch to BH-209 yet probably will not for some time down the line... to expensive for me. I did do a lot of load developement for the different rifles that I own. It worked out that 110 grains of T7-2f worked best in most of my guns, but the White and the Knight DE both shoot 120 grains. I also shot a Remington 700ML for years - the older version - a 24" barrel which might be a lot like the shorter barreledX7 and it really like 100 grains.
The Noslers haveprovided outstanding success and performance EASILY out to 200 yards from there you are stretching them.
I do not know if you have made the jump to BH but if not and you are still shooting T7 - you might even look at T7-3f for a cleanerburn anda bit faster acceleration of the projectile. It is just
slightly more suseptible (sp) to moisture in the rainand winterthan 2f (in theory) - I have never had a problem with either but others might.
.458/300 grain
Average velocity with 120 grains T7-2f has been 1860
Average velocity with 110 grains T7-2f has been 1775
and I will be darned I can not find the information for the old Remington with 100 grains of T7.
I have a lot of information about this subject if you want more let me know.
Chap wil find this post sooner or later and he is way more scientific than I am - so he will share valid reasoning - (he is a math nut) I hunt with a one of them and for them visual performance is not enough there has to be a mathematical answer to every equation or it just will not work...
